WARSAW, May 21 (Xinhua) -- Poland has requested an entry ban on Israeli National Security Minister Itamar Ben-Gvir, a foreign ministry spokesperson told local media on Thursday, after Ben-Gvir appeared in a social media video mocking detained activists from the Gaza-bound Global Sumud Flotilla.

Earlier on Thursday, Polish Foreign Minister Radoslaw Sikorski said on social media platform X that he had summoned Israel's charge d'affaires in Warsaw over the detention of flotilla activists, including Polish nationals, demanding their immediate release and an apology.

"Poland strongly condemns the treatment by representatives of the Israeli authorities toward activists from the Global Sumud Flotilla detained by the Israeli military," Sikorski wrote on X. He also advised Polish citizens against traveling to Israel and Palestine for security reasons.

The flotilla set sail from Türkiye's Marmaris coast on Thursday last week in a third attempt to break Israel's blockade of Gaza and deliver aid to Palestinians in the war-devastated enclave. Hundreds of flotilla members were brought to Israel's Ashdod Port on Wednesday after Ben-Gvir released a video showing some of them shackled and forced to kneel.

In the video, dozens of activists are seen kneeling on the floor with their heads bowed and hands bound behind their backs with zip ties while the Israeli national anthem blared over loudspeakers.

The Israeli ministry said the country would not allow any breach of what it called the "lawful" naval blockade of Gaza, describing the flotilla as "a PR stunt in the service of Hamas."

A group of European countries has criticized the Israeli treatment of the flotilla activists, many of whom are European citizens, condemning the humiliation of detainees as unacceptable and inhumane, and demanding explanations, apologies and the release of their citizens.
